CHECK ROWER FOR CORN-PLAN'l'ERSi SPECIFICATION forming part of LettersPatent No. 271,788, dated February'fi, 1883.

Application filed July 1, 1882. (No modelJ To all whom it may concern:

Be it known that I, ARTHUR W. CASE, of Decatur, in the county of Maconand-State of Illinois, haveinvented a new and useful Improvement inCheck-Rowers for Corn-Planters; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming a part of thisspecification.

This invention relates to improvements in number of parts andsimplify'construction,

lessening liability to get out of order; fourthly, to reduce frictionand avoid tendency to twistin g the seed-slide by the action of the camsof the reel-shaft upon the seed'slide; lifthly, to hold the reel-armsagainst movement only when acted upon by the knots of the checkrow lineor wire; and, further, in providing for the parting of the sections'ofthe checkrow line, to prevent its breaking when sub- V jected tounduestrain or meeting an obstruction, and in the ready application oftheknots to the said lineor wire. To these ends the nature of and theseed-slide-operating lever, having a frictional roll or ball andconnected to said shaft, cams arranged to act alternatelyon said ball orroll of the lever, and consisting each of two blades withoppositely-inclined faces,

said blades being secured upon opposite sides my invention consists,first,in combining with the reel-shaft adapted to clamp the wire betweenthem, the

sides of the knot being bent in, substantially as hereinafter more fullyset forth.

In the accompanying drawings, Figure 1 is a plan view of my improvedcheck'rower for corn-planters. Fig. 2 is.a side view, and Fig,

3 is a front view, of the same. Figs. 4 and 5 are detailed views of mycoupling, showing-it line and to such in sections.

In carrying out my invention, I employ, as usual, a shaft, A, havingbear-in gs in boxes a, fastened to the seed or corn boxes a of acornplanter. This shaft carries thereel B, having slotted or bifurcatedarms B, )rovided with lateral projections or flanges B at their outerends, and the cams for operating the seedslide lever, which will be morefully referred to presently.

G is a triangular bracket or support, which is sleeved loosely upon theshaft A, contiguously to the reel B, to preventits partaking of themotion of the said shaft. It maybe braced in position in any suitablemanner, the wire or line balancing it when not-braced.

Upon short axes or stndsat the lower ends of the arms of the bracket 0are hung pujlleys or grooved rolls 0, the forward pulley being adaptedto occupy a higher plane than the rear pulley. The latter are arranged ashort distancei'roin the plane of rotation of the reel and a littleabove a horizontal plane touching the lower side of said plane ofrotation. The purpose of this arrangement is to cause the line orwire,-which is passed as'usual over said .pulleys, to pass in a lineintercept ing the reel-arms to allow its knots to strike and operatesaid reel-arms. The line or wire passes through the slotsor'bifurcations of the reel-arms to enable its knots to act upon saidarms.

To thei'orward arm of the bracket 0 and the pulley-axis on that arm isapplied a lock or retaining device for the reel-arms. It consists of aplate or bar, D, loosely'placed on the aforesaid axis and held inposition by a spring,

D, said plate or bar having two arms, at d,

as applied to a continuous cheek-row wire or IOC one arranged close tothe periphery of the pulley and the other in theplane of the rotation ofthe reel-arms. The line or wire passes above and in contact with the arm(1, with its knots striking said arnn,it being assumed that the machineis in motion, whereby the arm (1 will .be pressed downward and forward,whence it will be disengaged from the reel-arms,'prelike manner operatedthe look. A stop, 6, fixed to the pulley-bracket 0, holds the lock inposition as against the action of its spring when not in use, or whenthe machine is being operated with its opposite side presented to the yline or cord.- The stop 6 also prevents the wire slide lever.

or line from being thrown off the pulley.

E E are the cams which operate the seed-' They are adj nstably connectedor sleeved upon the shaft A by set or adjusting screwsf. This permitstheir relative adjustment with the intervals the knots are placed aparton the line or wire, to cause them to correspondin gl'y affect the leveroperating the seedslide. These cams are each provided with two spiralpropeller-shaped blades, with their faces arranged in a relativelyparallel plane and facing in opposite directions, to permit one tostrike and pass the roll or friction-roller of the seed-slide lever onone side and the other to strike and pass the said roll of said lever onA the opposite side. This action of the cams llllparts a reciprocatingmotion to the lever F,

connected to the shaft A between the cams,

which in turn, bearing in the seed-slide G, transmits a similar movementto the latter to cause the dropping of the seed or corn. The roll orglobegof the lever F is capable of turning as it is struck by the cams,to lessen friction.

H is the coupling, which also constitutes the knot, a series of which isapplied at the re quired intervals throughout the check-row line orwire, one purpose ofwhich is to operate the reel, as above stated. Thesecouplings or knots, as indicated by their names, also eifect thecoupling'together of the wire or linesections where it is made insections. The knotor coupling H is made of malleable iron or othersuitable metal, and has apertured heads or ends, which are connectedtogether by parallel side pieces, upon which are formed, on theirinsides, offsets or plates h h. These plates or offsets are not arrangedin the same plane, and are adapted to lap one upon the other by strikingwith a hammer and bending in the sides ofthe couplings, as seen in Fig.4. With the wire or line passed through the apertures in the heads ofthe knots and placed between the offsets, and by treating the couplingin the manner just described, the coupling or knot is secured at thedesired point upon the line or wire. It will be also seen that where thewire or line is made in sections the links or sections are held in thecouplings by eyes formed on the ends of said sections. This arrangementallows the wire or line, when constructed in sections, to turn in theapertured ends of the coupling or knot, as a swivel. The eyes hold thesections or links as against pulling apart when subjected to only theusual strain; but the section will be permitted to straighten out andwithdraw from the coupling when subjected to unusual strain or uponcoming in contact with an obstruction, thus preventing the breaking ofthe wire or line, which may be again inserted in couplings or knot, theeye or eyes beingrestored, as before.

It will be further observed that this device is composed of few parts,and therefore not liable to easily get out 'of working order. It avoidsany tendency to twisting at the point of contact between the reel-shaftcams and the seed-slide-operatin g lever. It is applicable to machinesof this class regardless ofthe location of the reeland line or wirepulleys or thelength of stroke of the seed-slide-operating lever. Adirect and positive action is obtained between the reel-shaftand theseed-slide. Having thus described my invention, what I claim, and desireto secure by Letters Patent,

1. In a check-rower for corn-planters, the combinatioi1,with thereel-shaftA and the seedslide-operating lever F, having the frictionalroll or ball g,'and connected to said shaft, of

the'cams E, arranged to act alternately on the said roll or ball of thelever F, and consisting each of two blades with oppositely-inclinedfaces, said blades being secured upon opposite '7 sides of a sleevelocated on the reel-shaft, and having adj usting-screwsf, substantiallyas and for the purpose set forth.

2. In a check-rower for corn-planters, the combination, with the reel B,with'its arms B, provided with right-angled projections B ,-ot' thespring-lock or retaining device D, fitted loosely upon an arm of thebracket 0, and provided with an arm, 61, having a right-angledprojection, and with an arm, d, arranged contiguous to theline-pulley toadaptit to be struck by the knots thereof, substantially as and for thepurpose set forth.

3. The oheck-rower-line knot H, made rectangular and of malleable metal,with apertures in its ends and projections or ribs h on its oppositeinner sides, said projections or ribs be: ing disposed out of line witheach other and adapted to clamp the Wire between them, the

sides of the knot being bent in, substantially as and for the purposeset forth.
